I am loading 00 buck using this recipe.
Attachment 263544
Changing hulls or shot size is not an option. The problem I am having is the buckshot is causing bumps on the outside of the hull that are just large enough that they prevent reliable chambering.
Is trimming the petals off the wad, which would give slightly more inside diameter an option? Any other ideas?
Are you roll crimping?
No, star crimping.
Yes, or just us a gas seal then card wads to correct height. Come off powder a couple of grains.
You can roll your buckshot in alox or 45/45/10 lube let them dry then load them up. This will help to reduce the leading if any. I've reloaded brass shells without a plastic wad, used felt or fiber wad and over shot card to seal it up.
Some wads have more taper and thicker petals.
What hull is that load data for?
Win AA 1x Fired (Gray)
It's a long time since I loaded buckshot but I do recall getting 'lumpy' finished cartridges if I tried to crimp too tightly, with both star and rolled crimp. I wouldn't use card and fibre wads in a compression formed case (WWAA) myself as it's difficult to apply the required correct wad seating pressure due to the internal tapered case walls. Plastic wads aren't seating pressure sensitive due to their collapsing centre section.
I know you want to use the stuff you've got but I think I would try a different wad with a shorter mid section to reduce the crimp force as a first option.
you don't need a sleeve. I used 8 00 in a 2 3/4 hull, hot charge of maybe Herco and killed deer in their tracks at some long ranges. 000 would be even better.
Try the fit with the petals cut off the WAA12F114. Using 0 buck (what I've found in commercial 00 shells) makes life easier.
I'm loading red AA with Universal and the same wad/shot. You don't say if you're layering the shot or not. Mine are 3x3 layers, and each layer is just tight in the wad. My MEC will sometimes kind of crush the end of a hull if I just run it all the way down on one motion. My solution has been crimp a little, turn the hull, then finish it off.
The shot is Hornady brand that I picked up somewhere.
I had the same issue when trying to use Remington hulls, I resorted to removing the pedals from the wad and loading it that way. If you're worried about leading, you could use a mylar wrap.
I had 3 stacks of 3 give me fits and went to 4 stacks of 2 to get 00 to work with a wad. A punched 20 ga cardboard on top of the shot made the crimp more better. I rotary tumbled to take my buckshot diameter lose a couple thousandths. It got rid of the sprue nub too.
That is exactly the problem I had with 00 buck. So I switched to #1 buck and lost the problems.
The 00 is getting run through a lee .314 size die and loaded as plinking loads in a .32sw long with a #1 buck below it.
Does nice job on targets.
I'm sure he is layering in 2's, that's the only way 00 buck fits in a wad. More than likely your stack height is too high, and causing the crimp to push down on the shot. When you do this, the crimp is pushing down on the shot, which has no way to to except outwards. The easiest fix is to use more wad pressure, such that your crimp is merely closing on top of the shot, not compressing it.
Wad pressure was the fix.
Thanks Guys.
